Some toolkits, for example Jena [1], do support user defined XSD datatypes
by using a local convention for the URI of the defined datatype. The
problem, as you point out, is that there is no defined standard for this
URI convention and so any such usage may not be portable.
The semantic web best practices WG is, I believe, hoping to work with the
XML Schema WG to resolve this.
